BELT-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 251,892, dated January 3, 1882. Application filed November 21, 1881. (No modell.)

To all whom it may concern Be it known that I, PETER H. KEIM, a citizen of the United States, residing at Dixon, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Belt-Stretchers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to belt-stretchers; and it consists in the construction, arrangement, and operation of its various parts, the details of which will be hereinafter more fully set forth.

In the drawings, Figure 1 is a top plan view oi' my device; and Fig. 2 is a side view, showing cross-sections upon the lines a: w and y y, Fig. 1.

A A are the belt-keepers. Upon both ends are downwardly-projecting blocks or lugs, a, which have formed in their inner sides wedgeshaped grooves, in which slide the belt-wedges e', as shown. The grooves narrow from the inner side of the keepers outwardly, so that when the belt-wedges are inserted into-them under the belt they will press it firmlyagainst the keeper, as shown in Fig. 2. Upon the outer sides of the downwardly-projectin g lugs e are formed the pulley-blocks a2, in which are pivoled the pulleys a", as shown. l Passing around these pulleys are the ropes B B, which have their ends secured to the windlass G, as shown. At both ends of the windlass are levers c c, by which it is operated. Located centrally on the windlass is a ratchet, c', and journaled on the windlass on each side of the ratchet is a pawl, o2, depending from which is an arm or lever, c3, as shown.

Y In the operation of the device the ends D D of the belt are passed into the keepers from their outer sides. The wedges a a. are then placed into the wedge-shaped grooves of the lugs a and pressed firmly into them against the belt, which prevents it from slipping. 'Ihe windlass is then turned by the levers c2, which winds up the ropes B B, thus drawing the keepers together and stretchingthe belt. The pawl c2 engages with the ratchet c', and the end ofthe arm c3 bears againstihe belt, which prevents it from unwinding. The separate ends of the belt may then be placed together, after which the sretcher may be removed by drawing out the wedges and lifting the device from the belt.

What I claim is- 1. The belt-keepers A A, upon both ends of which are downwardly-projecting blocks or lugs a, w-hich have upon their inner sides wedge-shaped grooves, in which slidle the beltwedges a', adapted to hold the keepers firmly to the belt without slipping, said keepers being further provided upon the outer sides of the lugs a with pulley-blocks a2, in which are journaled pulleys a3, all arranged to operate substantially as and for the purposes specified.

2. The keepers A and their pulleys a3, in combination with the ropes B and windlass C, all arranged to operate as described.

3. The windlass G, provided with a ratchet, c, pawl c2, leverc, and ropesB, operating in combination with the keepers A A and their attachments substantially as and for the purposes specified.

In testimony whereof .I affix my signature in presence of two witnesses.

PETER H. KEIM.
